Application filed October 18, 1922, Serial No. 595,331."

'/'0 n.72 whom t may/concern lBe it knowuthat I, Jarras F; Buisman', a citizen of the United States, residing at Lombard, in the county of Du Page and State of lllinois, have invented new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to pumps particularly designed for use in connection with syrup or pharmaceutical jugs or bottles, and an object of the invention is to provide a pump structure designed for facilitating the dispensing of the contents of the jugs or bottles, which pump structure is small enough to be inserted through the neck of the jug.

Considerable difficultyl is experienced in dispensing the contents of syrup orphar1na-k ceutical jugs or bottles, and usually the contents or a portion of the contents of the jugs or bottles are poured into a second receptacle and dispensed from it.

It is an object of the present invention to provide a pump structure which may be readily attached to or detached from said jugs or bottles, and will permit accurate dis pensing of the contents of the jug directly therefrom as needed.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying drawing wherein Fig. l is a vertical section through a jug showing one of the improved pumps applied thereto, and showing part of the pump in section.

Fig. 2 is an enlarged View of the inner end of the pump.

Fig. 3 is a vertical section through a modified form of the pump showing it applied.

Referring more particularly to the drawings, the improved pump structure comprises a feeding tube l which projects centrally through a cork or stopper 2 adapted to fit snugly in the mouth of the jug A. The feeding tube l has a spout 3 which is hollow and communicates with the interior of the tube l. A handle or knob 4 is formed integrally on the tube l and has its axis in direct alignment with the axis of the tube 1, as clearly shown in Fig. l of the drawings. An annular flange or piston 5 is formed upon the lower end of the tube 1 and fits within the cylinder 6. A spiral spring 7 is placed within the cylinder 6 and urges the piston 5 upwardly. The bottom of the cyl vinder is cupped upwardlyl and is provided with aA pim-nay of niet apanage a to` per.- mit ,the syrup Lor liquid contents of the jug to pass into the cylinder. A valve I9 is prof vided for closing the openings 8 upon ,downthe tube l and outwardly through the spout l 3 to permit the dispensing of the contents of the jug. j

For convenience of assembly thecylinder 6 is made of sections 1l andk 12 which are connected by means of annular flanges 13. The valve stem 14 extends slidably through` the bottom of the cylinder 6 and has a relatively small head 15 upon its lower end to prevent displacement of the valve.

In Fig. 3 of the drawings, a modified form of the invention is shown in which the tube l is stationary and is formed integrally with a stopper 2 which stopper is adapted to fit snugly within the mouth of the jug B and has a valve flange 20 formed upon its outer end which covers the mouth or open end of the neck C of the jug B.

The tube l has its lower end flared as shown at 2l, which flared end opens out into knob 25 upon its upper end to facilitate its i operation.

From the foregoing description taken'in i connection with the accompanying draw` ings it will be apparent that either the pre. ferred or the modified pump structure may be inserted'through the neck or mouth of the I ordinary type of gallon jugs or bottles used in the marketing of Syrups or other druggist supplies, and that the contents of the jugs may be dispensed directly therefrom, through the medium of thepump structures, by reciprocation of the piston.

It is, of course, to be understood that the` invention may be constructed in other manners and the parts associated indifferent relations and, therefore, I do not desire to ing and further provided with a plurality of perforations around said opening, a piston on said tube and movable within said cylinder for forcing liquid outwardly through the tube and spout, a spring in said cylinder, a valve member having a stem movable through the central opening of the bottom portion for controlling the inletl and outlet of liquid into the cylinder, and a relatively small head upon the lower end of the stem to prevent displacement of the Q75 valve.

In testimony whereotl I affix my signature.

JAMES F. BRADLEY.
